Question

Determine the filter coefficients $h_d(n)$ for the desired frequency response of a low pass filter given by, $H_d(e^{jw})$ = $\left \{ {{e^{-j2w} -\frac{\pi}{4} \leq w \leq \frac{\pi}{4} } \atop {0} \frac{\pi}{4} \leq w \leq \pi }} \right.$ If we define new filter coefficients by, $h(n) = h_d(n)*w(n)$ where w(n) = $\left \{ {{1 for 0\leq n \leq 4} \atop {0 otherwise}} \right.$

Answer 1

The flowing liquid will always be very nearly pure solvent S. The product rho*Das can be considered constant, and the diffusion of A in S can be considered by a steady state version of the the continuity equation in terms of molar concentration (equation B.11.2). Note that the presence of a small amount of the reaction product B is ignored.
